WARNING LIGHTS
orElectronic parking

(yellow) (if so
equipped)
The electronic parking brake system warning
light functions for the electronic parking
brake system. If the warning light illuminates,
it may indicate the electronic parking brake
system is not functioning properly. Have the
system checked. It is recommended that you
visit an INFINITI retailer for this service.
For additional information, refer to “Elec-
tronic parking brake” in the “Starting and driv-
ing” section of this manual.
INDICATOR LIGHTS
orElectronic parking
brake indicator light
(red) (if so equipped)
This light illuminates when the electronic
parking brake system is operating.
When the ignition switch is placed in the ON
position, the electronic parking brake warn-
ing light illuminates. When the engine is
started and the parking brake is released, the
warning light turns off.
If the parking brake is not released, the elec-
tronic parking brake warning light remains
illuminated. Ensure the electronic parking
brake warning light has turned off before
driving.
If the electronic parking brake warning light
illuminates or flashes while the electronic
parking brake system warning light
or(yellow) illuminates, it may indicate
that the electronic parking brake system is
not functioning properly. Have the system
checked. It is recommended that you visit an
INFINITI retailer for this service.
For additional information, refer to “Elec-
tronic parking brake” in the “Starting and driv-
ing” section of this manual.

If you have a flat tire, refer to “Flat tire” in
the “In case of emergency” section of this
manual.
TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all tires
except the spare. When the low tire
pressure warning light is lit and the
“Tire Pressure Low – Add Air” warning
appears in the vehicle information dis-
play, one or more of your tires is sig-
nificantly under-inflated. If equipped,
the system also displays pressure of all
tires (except the spare tire) on the dis- play screen by sending a signal from a
sensor that is installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above
16 mph (25 km/h). Also, this system
may not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
For additional information, refer to
“Low tire pressure warning light” in the
“Instruments and controls” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving”
section and “Flat tire” in the “In case of
emergency” section of this manual.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label or the Tire and Loading In-
formation label under the “Cold Tire
Pressure” heading. The Tire and Load-
ing Information label is affixed to thedriver side center pillar. Tire pressures
should be checked regularly because:
∙ Most tires naturally lose air over time.
∙ Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
refer to “TPMS with tire inflation indi-
cator” in the “Starting and driving” sec-
tion of this manual.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WHEELS AND TIRES

WARNING
∙ Improperly inflated tires can fail suddenly and cause an accident.
∙ The Gross Vehicle Weight Rating (GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight ca-
pacity is indicated on the Tire and
Loading Information label. Do not
load your vehicle beyond this ca-
pacity. Overloading your vehicle
may result in reduced tire life, un-
safe operating conditions due to
premature tire failure, or unfavor-
able handling characteristics and
could also lead to a serious acci-
dent. Loading beyond the speci-
fied capacity may also result in
failure of other vehicle
components.
∙ Before taking a long trip, or when- ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level. ∙ For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

Tire and Loading Information label
1Seating capacity: The maximum
number of occupants that can be
seated in the vehicle.
2Original tire size: The size of the
tires originally installed on the ve-
hicle at the factory.
3Cold tire pressure: Inflate the tires
to this pressure when the tires are
cold. Tires are considered COLD
after the vehicle has been parked
for 3 or more hours, or driven less
than 1 mile (1.6 km) at moderate
speeds. The recommended cold
tire inflation is set by the manu-
facturer to provide the best bal-
ance of tire wear, vehicle handling,
driveability, tire noise, etc., up to
the vehicle’s GVWR.
4Tire size - refer to “Tire labeling” in
this section.
5Spare tire size.
6Vehicle load limit: Refer to “Ve-
hicle loading information” in the
“Technical and consumer informa-
tion” section of this manual.

Checking tire pressure
WARNING
∙ Driving at high speeds, 100 mph (160 km/h) or higher sustained
where it is legal to do so, can cause
tires to have excessive heat build
up, which may result in a tire fail-
ure causing loss of control, crash,
injuries or even death. ∙ Some high-speed rated tires re-
quire inflation pressure adjust-
ment for high-speed operation.
When speed limits and road condi-
tions allow vehicle driving at high
speeds, make sure tires are rated
to support high speed operation,
tires are in optimal conditions and
pressure is adjusted to correct cold
inflation pressure for high speed
operation.
∙ If your vehicle is equipped with P235/55RF19 or P255/45RF20
tire sizes, tires require adjustment
to the inflation pressure when
driving the vehicle at speeds of
100 mph (160 km/h) or higher
where it is legal to do so. Set the
cold inflation pressure to 36 psi
(250 kPa).
∙ After vehicle high speed operation has ended, readjust the tire pres-
sure to the recommended cold in-
flation pressure, For additional in-
formation refer to the "Checking
tire pressure" section of this
manual. 1. Remove the valve stem cap from
the tire.
2. Press the pressure gauge squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position the gauge to eliminate
this leakage.
3. Remove the gauge.
4. Read the tire pressure on the gauge stem and compare to the
specification shown on the Tire
and Loading Information label.
5. Add air to the tire as needed. If too much air is added, press the
core of the valve stem briefly with
the tip of the gauge stem to re-
lease pressure. Recheck the pres-
sure and add or release air as
needed.
6. Install the valve stem cap.
